-Chitin is a structural carbohydrate that forms their exoskeleton
Explanation;
-Chitin is the main component in the exoskeletons of arthropods and crustaceans and is also in the cell walls of fungi.
-It is a linear long chain polymer consisting of repeated units of N-acetyl-glucosamine.
-The main function of the chitin-containing exoskeleton is to keep the inner soft tissue safe from any sort of injury and also prevents the delicate tissues from drying (acts as a water tight barrier against dehydration).
Answer:
Water cycle is also called hydrological cycle. In this cycle water moved continuously above the surface of the earth for the continuity of life. Water is evaporated from the sea and ocean in the process of evaporation. This water goes to the atmosphere and form clouds.
